FINISHING-MACHINE FOR THE USE OF SHOE-COBBLERS.

Specification of Letters Patent.

Patented Nov.. 13, 1906.

Application filed December 9,1905. Serial No. 291,103.

ishing-Machines for the Use of Shoe-Cobblers, of which the following isa specification.

My improvement relates to that class of machines used by cobblers orshoe-repairers.

for finishing rep air-work.

The object of my invention is to provide a cheap, light, compact, andportable machine to be operated by foot-power, adapted to carry severalcutting and polishing wheels, which can be easily adjusted and changed.

The manner in which I accomplish my ob ject is described in thefollowing specification and illustrated in the accompanying drawings.

Figure 1 is a front elevation of the machine; Fig. 2, side view.

The frame A, forming the main body of the machine, is constructed of onepiece. The lower rear part of this frame is adapted to contain a set ofbearingboxes B. J ournaled in these boxes is a driving-shaft C, adaptedto support a driving-wheel D. On each end of this shaft a disk E isattached. Each of these disks is provided with an adjustable crank-pinF. Pivotally attached to each of these pins is a connecting-rod G. Thelower end of each of these rods is pierced with a number of holes H,arranged in a vertical line. Pivotally connected with the lower end ofeach of these rods is a horizontal lever I. These levers are pivotallyconnected with the rear legs of the frame A and are connected with across-bar J at the front of the frame, thereby forming a treadle. Eachof the levers are pierced with a number of holes K and L, arranged in ahorizontal line. These holes, in connection with the holes in theconnecting-rods, permit of the adjustment of the treadle both verticallyand horizontally.

The upper part of the frame A is inclined forward, as shown in Fig. 2,and is adapted at the upper end to support a set of bearingboxes M.These boxes are adapted to slide vertically in the frame and to supporta spindle N. This spindle is provided with a pulley O, adapted to beconnected by a belt or chain P with the driving-wheel and withadjustable collars Q, adapted to form bearings against the boxes M.Supported on this spindle are several grinding and polishing wheels R,separated by sleeves S, which are of various lengths and adapted to slipon and off the spindle and which, together With the wheels R, aresecured on the spindle by the nuts T on the threaded ends of thespindle. Beneath the boxes M and pivotally attached to the frame H aretwo eccentric levers a, which are adapted to support the boxes M in theposition required when the machine is being operated and to lower themand the spindle so the belt or chain can be removed from thedriving-wheel and the spindle be removed from the frame altogether. Thepivot-studs v, on which these levers are supported, are adjustablevertically in the slots indicated by the dotted lines, and therebypermit the adjustment of the spindle, so as to secure the desiredtension of the belt or chain connecting the spindle with thedriving-wheel. The stop-pin w is adapted to engage and hold the levers uin position.

What I claim, and desire to secure by Letters Patent, is

1. In a machine of the kind described the combination consisting of aframe A, the lower part of said frame being adapted to support a pair ofbearing-boxes, a pair of bearing-boxes B supported in the lower partof'said frame, a shaft C supported in said bearings and said frameadapted to be revolved therein; a driving-wheel D supported on saidshaft adapted to be engaged by a belt or chain; a pair of disks Eattached to said shaft, one at each end; a crank-pin F adjustable,secured in each of said disks; 2. pair of connecting-rods G pivotallyattached to said crank-pins, each of said rods being pierced with aseries of holes H arranged in a vertical line; a pair of horizontallevers I, pivotally attached to the rear legs of the frame, and to saidconnecting-rods, each of said levers being pierced with series of holesK and L, said levers being connected together by a crossbar J; a pair ofbearing-boxes M supported in the upper end of the frame A and adapted tobe adjusted vertically therein; a spindle N supported in said boxes; apair of collars Q adapted to hold said shaft in position in said boxes;a pulley 0 attached on said spindle adapted to support a belt or chain;a belt or chain P attached to and connecting said pulley with saiddriving-wheel; a pair of eccentrio levers u pivotally supported on saidframe adapted to be moved and to support and adjust said bearing-boxesand said spindle and thereby adjust the tension of the belt or chain P;a pair of adjustable pivot-studs v adjustably secured in said frame,adapted to support and to adjust the position of said eccentric levers;a pair of stops w afIiXed in said frame, adapted to hold said eccentriclevers in position; a plurality of sleeves S, adapted to slide freelyover said, spindle; and suitable Wheels for grinding and polishingadapted to be supported on said spindle; substantially as described andfor the purposes specified.

2. In a machine of the kind described the combination consisting of aframe A; a pair of bearing-boxes B, supported in the lower part of saidframe; a shaft C supported in said bearingboxes; a Wheel D supported onsaid shaft; a pair of cranks E attached to said shaft; a pair ofconnecting-rods G attached to saidcranks, having a series ofholes Harranged in a vertical line; a pair of levers I pivotally attached tothe rear legs --of said frame and to said connecting-rods and havboxes Msupported in the upper part of said ing a series of holes K and L andbeing connected together by a bar J; a-pair of bearingframe; a spindle Nsup orted in said boxes and provided With a pul ey O and adapted tosupport grinding and polishing Wheels R; a 1

supported on said shaft; a pair of cranks E 7 attached to said shaft; apair of connectingrods G attached to said cranks; a pairof le vers Ihaving a cross-bar J; said levers being pivotally attached to said frameand to said connecting-rods; a pair of bearing-boxes M' supported 1nsaid frame so as to be moved vertically therein; a spindle N supportedin said boxes ada ted to support one or more polishing-whee s Randhaving a pulley O a belt P connecting said pulley and said Wheel, and apair of eccentric levers supported on said frame, adapted to support andmove said boxes and spindle vertically in said frame, substantially asdescribed and forthe purposes specified.
